JOHN W. KELLER, 0F PERU, IOWA.

WIRE-STRETGHER.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed July 22, 1914. Serial No. 852,368.

To all whom it may concern:

Be it known that I, JOHN W. KELLER, a citizen of the United States, residing in Peru, county of Madison and State of Iowa, have invented a new and useful Improvement in Wire-Stretchers, of which the following is a specification.

This invention relates to wire stretchers and has for its object to provide a clamp member therefor, which may be quickly and firmly secured to the wire at any desired point, operating means being applied to-the clamp to stretch the wire.

A further object is to provide such a device in a simple, strong, durable and inexpensive construction.

My invention consists ofcertain details of construction hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings in Which Figure I shows my device secured to a fence wire, the chain of a stretcher being joined to the clamp. Fig. II shows a side elevation view of my device, in enlarged detail, secured to a piece of wire; Fig. III shows a transverse sectional view of the same. Fig. IV is a detail perspective view, partly broken away and in section.

Referring to the accompanying drawings the reference numeral 10 indicates the body portion of my device which is composed of a metal piece provided with hooks 11 and 12, one on each end thereof.

The numerals 13 and 14 indicate depending members, located centrally of the body portion, said members being joined together at their upper extremities and spreading apart as they depend, so as to form a wedge, as clearly shown in Fig. III.

The numeral 15 indicates an orifice extending transversely through the member 13 and a like orifice 16, in line with the orifice 15, extends transversely through the member 14:.

The numeral 17 indicates a wedge shaped pin, designed to be inserted into, and extend through, the orifices 15 and 16;

In practical operation the wire to be stretched is inserted between the members 13 and 14, the wedge shaped pin then inserted in its orifices under the wire. The pin is then forced, ordinarily by pounding, farther into the orifices thus forcing the wire upward and firmly clamping it, as is clearly shown in the drawings. A stretching means is then applied to one of the hooks 11 or 12, according to the direction in which the operator desires to stretch the wire.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

1. In a clamp, a pair of members connected at one end and diverging at their other ends so as to form a V- shaped space therebetween, said members having slots which latter extend above the apex of the V-shaped space, and a wedge receivable in the-slots and extending transversely. across the V-shaped space so as to arch the article gripped so that the arch extends into the space formed by the slots and above the apex of the V-shaped space.

2. In a clamp, a bar having a V-shaped member connected at its apex to a point central of the length of the bar, said mem her being slotted and the slots extending beyond the apex of the member-andinto the bar, and a wedge extending through the slots to arch the article gripped so that the arch extends into the slots and above the apex of the V-shaped space.
